BOLTR: Dyson V9 Motor. ALIEN TECHNOLOGY CONFIRMED?! 

such a delightful combination of profanity and knowledge

Neodiddlium! osmelloscope! while this is chooching! These words and expressions are in my vocabulary now!

Dyson Vacuum next, I want you to investigate their bullshit with their suction technology

I wouldn't have dropped out of my electronic engineering degree if I had you as a lecturer/ lab lead

The low emf does NOT mean it is not a brushless DC motor. The emf is more or less proportional to the RPM and must be compatible with whatever voltage the motor will be supplied with when running. That particular motor is meant to run at tens of thousands of RPM while you are cranking it at probably one or two thousand RPM so I would not expect it to generate more than one volt. If you look at the type of motors used in RC airplanes, drones and such they have a 'KV' rating which specifies the RPM achievable per volt. These can vary from about 500 to 20,000 typically. At KV 20,000 motor may be rated at 80,000 RPM running on a power supply of 4 volts. Such a motor would typically be in a micro drone with a single cell LiIon battery. More typical for a medium sized drone would be a KV=900 motor which would do, say 13,000 RPM at 11 volts. If turn the shaft of such a motor at 1000 RPM with an electric drill it will generate less than 1 volt p-p of EMF. I think what you are seeing is just that.

You are fine, just... fine!

The 1 volt out is probably because it's designed to spin at 100krpm and you're giving it 300...

It's called a 'switched reluctance' motor. They're very cool, but not alien techology. They create a very fast rotating magnetic field within the rotor using the external coils. The rotor contains a special arangement of magnetically 'soft' and 'hard' (typically ferrite and transformer iron) materials that gets dragged around due to magnetic induction. This sets up eddy currents within the rotor which act like magnetic gear teeth. It is this gearing effect that allows the motors to reach such extermely high speeds. The fan is taken from the design of small turbofan jet engines, which been the subject of incredibly rigourous research because of their uses in transportation, energy comversion and war. Also amazing, but well researched.

Man that's most poetic swearing that I have heard. And I know lots of Russian welders. )))

Urban dictionary would benefit greatly from you.

100w in that size isn't too surprising considering how much air they've got going through it. I wonder if the failure to chooch in the vice might be because it's seeing the revs rise too quickly due to lack of air resistance from the housing.

thanks for paying+providing my education, dad

I spend quite a bit of my time in bed watching videos on RU-vid. A buddy of mine showed me your videos a few weeks back and I gotta say... You are definitely one of the most educational and informative creators on RU-vid. You are also one of the most entertaining. Thank you for every video you have posted.

13:11. highlight of the video my guy

I've heard other folks on here mention AvE, but it took me months to finally watch an AvE video. I've been missing out! Might have to adopt Neodydlium!

n e o d i d d l y m a g n e t

The waveform is Class D mode B (pulses both high and low, thus having a "common mode" component). And I'm sure they are NdFeB magnets... The magnets are unplated, but passivated. Hobby motors use similar magnets with a similar surface treatment. The reason the back EMF voltage was low is because the number of turns on the coil is made low, to keep motor inductance low, to work well with the 30kHz switching waveform. What's so special about the motor is that there are not multiple "phases" as would commonly be the case with a typical brushless DC motor (for example 3 phases). Here there is only a single phase. The motor is started by the torque supplied by the coils, but pulling (initially) against the strong cogging torque.

Love your jargon man. Neodiddlium is the type of magnet Ned Flanders uses.

Great and informative , people need to chill out and let the man be and express him self in any way he feels he wants to , people focusing on his accent changes and giving advice on how they want to hear it, that's not good , if you kill people's natural creativity you kill part of them , reversing what you actual want to achieve , open mindedness is the only way new information can be passed and received . Let it be . Keep up the good work .

Perfect cross between an Engineer with the vulgarity, of a sailor...

JFM is now how I will describe anything I don't understand.

God, I love this guy!

I'd love to hear an episode in nothing but AveSpanish (a treat especial!), AveGerman and AveCanuckFroggyLingo.

"there is probably a hundred thousand people that watched this video..." 1.2M and still counting :D

Obviously Apprenticed to the Great Stanley Unwin of England...Love this channel, love this guy's erudition, bravo !

Easiest subscription on UTub I've ever clicked. ...was like listenin' to your buddy talk. cheers.

old man ave throwin up some dank memes

Did dyson take the same thing as their "silent" room fans and use it in this hair dryer? Would be really cool if you could emulate that 30khtz wave and get the motor screaming again.

LOL, "Focus you FUCK!".

I just learned something for free and had a great fucking time doing it ... I love this guys lingo . It's not quite english but I get it .. love it! Subbed

Reluctance motors are composed purly of soft magnetic materials resulting in no cogging when the excitation windings are unpowered. For very high speed brushless motors you need both a high excitation voltage and a low stator inductance. This low inductance can be achieved by a low winding number. This will explain the small induced voltage when you turn it at low speed.

The way that motor is designed reminds me of the sensored brushless motor in my RC truck. Runs at 12.6V pulling 20A. Size of a D-Cell. It's mental.

YOUR electronic wizardry is only surpassed by your profane eloquence... You have me sir, I yield... Count me subscribed!

13:08 this is truly one of the most incredible videos on RU-vid.

LMAO! Brilliant guy. My first exposure. Needs his own Cable show!

A V2 rocket joke? This is the joke for me, this is why I'm here.

Probably the best informative and entertaining technobabble I've randomly watched.

360 degrees is 2π right ?

I've learn't pretty much everything I know from you, sir. Thanks for letting me hang out with ya and have a few beers and laughs.

I understand 1/3-1/4 of the subject you're discussing, yet still find myself watching videos and laughing. Bravo.

I think the jargon gets thicker with every video. He's just BARELY speaking speaking English by now. Another five videos or so, and "AvEnish" will be an entirely separate language.

hey AvE hook that to one of your power rectifiers and crank it up till it lets out the blue smoke

Believe me when I say I've never seen anything of yours nor do I know how this got on my homepage. But I like it.

I don't care what this video is about, I just kept watching it to listen to this guy talk..... very entertaining.

Loving the combination of invented words, technical knowledge and just general give-no-fuckery it's a refreshing change keep up the good work sir!

what happens when you plant the dyson in the ground when you're done

'Reluctance motor' sounds like one of your made-up terms!

Hey AvE love the combo of brains and bullshit, just not sure of the ratio.

Elegant profanity and I was entertained! Nice one!!

I literally understand none of this, yet it is very interesting to sit here and learn from your videos. Very informative yet it won't put me to sleep.

neodidlyium

I laughed; I learned. This is what youtube is for.

now use it to inflate a miniature wacky waiving inflatable arm tube man

I only understand about a 1/3 of what you are talking about , but really enjoy trying to learn a new language from such a great teacher

Holy crap, that's so crazy tech right there. The machining on the fan alone is amazeballs. But, I cant get over the PWM frequency. How some P and N material can turn ON and OFF 30,000 a sec so accurately, is just beyond my comprehension. I work with old servos and CNC stuff alot, but this really blew me away.

Nothing alien just clever British engineering.

13:11 subscribed forever.

is there an AvE drinking game? Its got what drunk nerds crave.

As a magnet specialist, I can confirm the magnet on the rotor is a neodymium multipole ring magnet.

you should make a t shirt that says "it's all just 1s & 0s" and have a smoking power tool in the background.

I figure all that air blowing on those long funny windings has something to do with being able to handle 100 watts.

IT'S ALL RIGHT THERE SHEEPLE! WAKE UP! LOL great laugh this morning.

Every time. I learn something new, and I get a good laugh. Thanks man.

Actually, the low voltage is due to the motor being designed to run at high rpm. It's engineered to hit 110k rpm at its operative voltage, therefore you'd have to reach that rpm to get the voltage out of it. Your drill simply doesn't have the rpm output to get the voltage up. Also the voltage measurement could be off by measuring across two phases only give 66.7% of the voltage. Your stepper motor is engineered to operate at very low speeds, which is why you can get voltage from it by spinning it with your hand.

Can someone explain to me what that green exray paper thing is, it's really interesting.

Thanks for the free edumakation! :D

There are plenty of brushless motors for RC planes and especially multicopters that have very low back emf constants, like 300-500 rpm/volt. So unless your drill can do 1000+ rpm it's not that surprising to see only 1-2v out. It's also not uncommon to see small motors like that (150-200 grams) rated for 300+ watts (maybe optimistic, but they too have exposed windings with a lot of surface area and air moving directly across them) That said, I don't see anything on the board that makes it obvious what kind of motor or drive topology they're using. Especially confusing to see only two power transistors and two wires going out to the motor. Is the blue box a film cap? How is it connected - in parallel with the electrolytics or something else? Does the motor have any cap out there with it (like a single phase AC motor)?

You are wrong! This is a brushless DC with a neodymium magnet core! Speed is monitored by a Hall sensor and controlled by a 8-bit microcontroller switching with a h bridge of mosfets.

Quite possibly the most clever free flowing monolog master on RU-vid.

Gotta say, as a new green maintenance worker, I love your lingo. You talk like my elder maintenance coworkers.

I didn't understand half the shit you said, but I couldn't stop watching. Subbed and liked

AvE has been identified. neodiddlyum. AvE is ned flanders.

"Sorry, fascism on the brain"

I didn't understand a single technical word that you said but listened spellbound all the same. In actual fact I like to break down all kinds of things like old burner units, PC's, printers, old garage engine tasting equipment, sound & graphics cards etc to remove all the old copper but mainly to collect and keep the motherboards, leaving the copper & gold in place. I fixed them on my wall to make a big piece of artwork. I then ran out of wall space so I took it all down and will be fixing them to separate sheets of multi-ply for more transportable art. In the process of dismantling I get a better idea of how things work and watching your film helps to further my understanding a bit plus learn new great words like 'neodidlium'. So thanks for that.

I've learned more watching you this last few months than I did in an entire year in JobCorps studying electronic assembly back in 85' Simple disciption of materials and process of disassembly spoken with humor and self-deprication.👍

WOULDN'T THE ABSENCE OF BRUSHES PROVE IT'S A BRUSHLESS MOTOR

I'm in an electricity class in college and I actualy know what your talking about lol

Not to mention 500 dollars spread across 100,000 people who almost definitely never buy this hair dryer, or take it apart..

This guy just packed so many epic phrases and expressions into 14 minutes of video, I would listen to him talk instead of music. +1 subscribe from me.

2:05 "Bumblefuckery" = Sub

The pulsification of your bridge rectumificator is intensely preportional to the pulsification of the p.l.c. ac to dc.lol🤣🤣

Hold the subject closer to the board to keep it in focus...... Y. F!

It takes a 🇨🇦'n to understand a 🇨🇦'n❗️😂😂😂 cheers from ThunderBay,Ontario,🇨🇦 Luke

If I watch enough of his videos and I get 1% of his knowledge through osmosis, I consider that a win.

You have my subscription because I think people who explain serious subjects with profanities using various accents cannot tell a lie.

Your German is incredible!

Oh man, after I stopped laughing and learning, I subbed you, brilliant! 👍😎

LOL Comedy and tech... love it. SUBSCRIBED

I still think that once the smoke escapes the unit is kaput. This was so enjoyable, brushed motors, brushless motors, reluctant motors all combined with alien technology. Just an amazing video. Thank You

It's official, BOLTR you are Bill Nye the Science Guy of this decade! Don't worry Bill you shall be inducted into the hall of fame as an entertainer of science education and be spoken about for generations to come.

Does the Dyson patents not describe the construction and operation of the motor?

Ever thought about doing Human Anatomy vejayos?

Damn...I loved this video, the commentary had me laughing throughout, your wordplay is awesome!

I think we're hoop a jooped? Your mastery of technological language is astonishing. You've made a fan.

Research motor Kv rating. The motor put out squat for voltage because it's designed to spin many thousand of rippems for each volt applied, so spun as a generator, you need to spin it many thousand rippems to get 1 volt out.

New favorite word... Bumblefuckery.

Nice math at the end of the video. Enjoy your video not just for the edumacation. But for the funny bits too. Learning can expensive if you do it right, like at university.

AvE, Shop Tour?

I wished someone did something like this for the V10 or V11 motors.
